Had my powerhead rebuilt a few months back. Excellent rebuild and he did a great job. Now it seems other things are happening.

Couple weeks ago a switchbox went out on me leaving me stranded on Toledo Bend. Got that fixed.

Took off yesterday and after about a mile it slowly dropped in rpm's and died. Seemed like a fuel delivery issue. I just started fishing as I am getting frustrated. when I got ready to troll back in I decided to check it out. It starts just fine and then dies. I can get it to keep running for a little while if I give it some throttle but,only did that once. Don't wanna screw anything up.

Yesterday I put a fuel pressure indicator on it.

Reads right at 36 when pump turns on. Cycled it back on and started it immediatly and it starts, idles, and dies before the pump ever turns off maintaining the 35 to 36 psi. I also pinched off the return line at the regulator so it gets maximim pressure. Still dies. I checked for water in fuel. None. drained the vst canister which was cleaned out on rebuild. Clean and no water. Plugs are good and every cylinder gets fire.

I need to rule out the kill switch and ignition switch but do not know the procedure. If anyone knows how to do this I would appreciate it. Then I can rule out those two items also.

Turned out to be the ECM in case anyone has a similar experience. After checking everything out and finding nothing wrong except for the way it ran and stopped I drove 3 1/2 hrs. one way to the person that built my powerhead. He had an ecm on another engine that he could plug in to see if it was the problem. Bad news but, at least I know what the problem is now.

That is gonna put a dent in my wallet!!
